in the last picture in the prior post you can see a rats nest of wires from how I kinda just haphazardly wired it so I decided it was time to clean it up, and mount the electronics better then they originally were.
This was my solution



It is a box I made to hold the LED controller, and the RX. I designed it to wrap around the rear shock towers.
The rear shock toweres also were redesigned for this to allow it to go on easy as I removed the body mounts as they are not needed for this RC, and also to make it stronger as one of the old shock towers were broken due to how thin the mounting tab was. The redesign made the tabs 4x thicker to where I doubt they will ever break. The front also has a new design based on the rears.

The box is made to be as water tight as I could get it. I made it in 2 halves, and took door, and window sealing tape, and put a strip on the top, and bottom with 4 screws (one in each corner) to hold it shut. This allowed me to easily put the pile of wires through.
How water tight is it? I don't know, but it would at least prevent any water getting in outside total submersion to which there is a high chance it wouldn't leak for a foot or 2 due to how much I compressed the sealing tape when I screwed the top to the bottom.
I also put the power switch for the ESC in an easily accessible location right behind the rear shock tower. I'm thinking of looking for a rubber piece I know I had somewhere on a RC to cover it from liquid, and debris though.
